Is clock speed divided amongst cores?

It seems like in general, a higher clock speed will beat more cores for most applications. But is the case such that each core runs at a fraction of that clock speed and the final speed is additive?
I had a Phenom 9650 four core and 2.3Ghz, which I upgraded to an FX-8300 8-core at 3.3Ghz. Does that mean on the Phenom, each core was running at 2.3Ghz OR 575Mhz? And on the current CPU< is each core @ 3.3Ghz, or at 412.5Mhz?

No its not divided , in an 8300 you have 8 cores all at 3.3ghz.

Under heavy use (if you run stock settings) fx chips are capable of 'intelligently' boosting speeds on a set number of cores while lowering non-used ones.

For example your 8300 can run 4 cores at 3.8ghz & 4cores at 3ghz OR 2 cores at 4.2ghz & 6 cores at 3ghz depending on core loads.

Core speed isn't everything though...You can have a newer CPU with newer architecture rated at a lower clock speed compared to an older CPU, but will still outperform older CPUs with higher clock speeds. What a CPU can calculate per cycle is just as important as the speed it operates at.
